“…If the reactions at the surface are under diffusion control, the fitting protocols discussed earlier cannot be used. Some work has been done to quantify systems of this nature involving iron 33 and copper, 34 but these have focused on a limited material scope or decoupled mass transport effects by introducing convection to the system. The agreement between corrosion current densities determined from both branches is also strongly dependent on experimental conditions used, such as the electrolyte and the scan rate.…”

Potentiodynamic polarization curves are often performed to characterize the bulk corrosion properties of a material in terms of its corrosion potential, rate, and Tafel kinetics in a given environment. This requires approaching them as one of two extreme cases, with purely activation or diffusion controlling the measured currents. For the intermediate behavior displayed by many real samples, making this assumption is a significant source of error. In this work, a finite element model has been developed which considers both of these contributions simultaneously for experimental data with a broad material scope. This has been used to examine both extremely corrosion vulnerable samples in two magnesium alloys and extremely corrosion resistant samples in two steels. The effectiveness of several goodness of fit statistics in comparing the similarity between experimental and simulated data has also been assessed.

“…Previous studies 43,44 , confirmed that the co-existence of sulfide and oxygen highly accelerated the corrosion rate of nickel and nickel alloys. This fact explains the results of surface analyses which indicate the presence of copper nickel sulphide and nickel sulphide as corrosion products for Ni-Cu corrosion in seawater.…”

Comparison of corrosion behavior of Ni, Cu and 70/30 Ni-Cu alloy together with that of carbon steel in seawater has been investigated. Characteristics such as morphological changes and composition of corrosion products have been studied comparatively by means of scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and X-Ray diffraction (XRD). It was found that both the protective properties and adherence of the film, formed on the surface depend on the nature of the substrate and the environment composition. Corrosion mechanisms for all the studied materials were suggested based on the surface analyses. The results show that the chloride content is the controlling factor in corrosion of both carbon steel and copper in seawater, while sulphur content is the regulating factor for corrosion of nickel and 70/30 Ni-Cu alloy in seawater.

“…In the presence of inhibiting anions the decrease in corrosion rates of the alloy may be due to the formation of cuprous oxide, Cu 2 O, which was further oxidized to a less protective hydroxy chloride (paratancamite) according to the following equations [1,[22][23][24] 2CuCl [25] . As Cu 2 O and Cu 2 (OH) 2 Cl may be formed by the above mentioned reactions (17)(18)(19).…”

“…(3), the values of E pit are deduced for the different NaCl concentrations and listed in Table (2). The previous studies carried out on the pitting corrosion in NaCl media reveal that there is a straight line relationship between E pit and log − Cl C in the following form [8][9][10] E pit = a 1 …”

“…This related to their corrosion resistance (mechanical workability, excellent electrical and thermal conductivity and resistance to macrofouling [1] . However, under some exceptional conditions, pitting corrosion of copper and its alloys may occur, especially in the presence of certain anions such as chloride, bicarbonate, sulphate, nitrate and others.…”
